Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lidocaine is a sodium channel blocker that stabilizes the neuronal membrane by inhibiting the ionic fluxes required for initiation and conduction of impulses, resulting in local anesthetic and antiarrhythmic effects.
Lidocaine is an amide-type local anesthetic that stabilizes neuronal membranes by blocking voltage-gated sodium channels, thereby inhibiting the initiation and conduction of nerve impulses.
Intravenous infusion: 1-4 mg/min (0.2% solution = 2 mg/mL) for antiarrhythmic therapy; loading dose 1-1.5 mg/kg IV bolus, then infusion. Maximum infusion rate 4 mg/min.
Apply up to 3 patches topically once daily for up to 12 hours per day. Maximum 3 patches (210 mg lidocaine) per day.

Terminal elimination half-life is approximately 1.5–2 hours (mean 1.8 h) in adults with normal hepatic function; may be prolonged in patients with hepatic impairment (e.g., cirrhosis) or heart failure (up to 10 h), and in neonates (3–6 h).
1.5-2 hours (terminal); prolonged in hepatic dysfunction or heart failure
Renal excretion of unchanged drug and metabolites accounts for >95% of elimination, with ~10% as unchanged lidocaine and ~90% as metabolites (primarily 4-hydroxy-2,6-xylidine, with minor contribution from monoethylglycinexylidide and glycinexylidide). Biliary/fecal excretion is minimal (<1%).
Renal (80-90% as metabolites, <10% unchanged), biliary/fecal (minor, <5%)
